I'd also like to highly recommend Dr. Mather's tutorials. They saved me an incredible amount of frustration and time, I only wish I'd found them sooner!

I'd also recommend trying to find someone proficient in the CAD program of your choice in your immediate area. A 30 second, "How do I do this?" kind of Q/A can save you hours and have a dramatic impact on the steep initial learning curve of many of these packages.

Plus, and take this to heart, it can keep you from developing some very bad habits....

To learn inventor, I would go to the "Built by Design" videos that were made by seven FIRST robotics students this summer. I hope they can help you learn inventor.

Re: how to learn inventor
 

I am just learning how to use inventor myself and I have found the tutorials to be very helpful. Practice what you learn by building various household objects, such as tables and chairs at first, but then move on to more detailed designs. I have even built my guitar.

Hope this helped. :D
